CAMBRIDGE, MA -- With help from an artificial language network, MIT neuroscientists have discovered what kind of sentences are most likely to fire up the brain’s key language processing centers. The new study reveals that sentences that are more complex, either because of unusual grammar or unexpected meaning, generate stronger responses in these language processing centers. Sentences that are very straightforward barely engage these regions, and nonsensical sequences of words don’t do much for them either. For ...

New York, NY [January 3, 2024]—Driven by the need for a better way to prioritize targets for drug development, the Icahn School of Medicine at Mount Sinai has led the development of a novel “genetic priority score” (GPS) that will integrate various types of human genetic data into a single easy-to-interpret score. The findings were described in the January 3 online issue of Nature Genetics [DOI: 10.1038/s41588-023-01609-2]. Studies have shown that drugs have an increased likelihood of success in clinical trials when ...

Alaska is on the front lines of climate change, experiencing some of the fastest rates of warming of any place in the world. And when temperatures rise in the state’s interior—a vast high-latitude region spanning 113 million acres—permafrost there not only thaws, releasing significant amounts of its stored carbon back into the atmosphere where it further accelerates rising temperatures, but it decays. This decomposition has the potential to infuse above- and belowground food webs with carbon, which can affect ...

Disease-causing bacteria of the genus Salmonella or Yersinia can use tiny injection apparatuses to inject harmful proteins into host cells, much to the discomfort of the infected person. However, it is not only with a view to controlling disease that researchers are investigating the injection mechanism of these so-called type III secretion systems, also known as "injectisomes". If the structure and function of the injectisome were fully understood, researchers would be able to hijack it to deliver specific drugs into cells, such as cancer cells. In fact, the structure of the injectisome has already been elucidated. ...

MAGs, predominantly in 1(3)-MAG form, and DAGs, with 1,3-DAGs as the more stable isomer, are crucial in food, cosmetic, and other industries. While MAGs are vital emulsifiers, comprising 75% of global production, DAGs are known as functional cooking oils that can reduce body fat and serum TAGs. However, their natural concentration in oils is low, prompting extensive research into their chemical and environmentally-friendly enzymatic production. Recently, a review published in the Grain & Oil Science and Technology journal on 2 November 2023, has shed light on the advancements in enzymatic production methods with special efforts on practical and ...

In Hawaiʻi and across much of Oceania, Pacific Islanders celebrate the connections between their islands and the ocean that surrounds them. “As descendants of the ocean, the dearth of Native Hawaiians and Pacific Islanders (NHPI) in ocean science seems inconsonant,” writes a team of authors that includes University of Hawai‘i (UH) at Mānoa faculty, students, and alumni in an article in a special issue of the journal Oceanography, “Building Diversity, Equity, and Inclusion in the Ocean Sciences. The authors ask, “Where are all our island people in the ...

In China, national parks represent the country’s most unique natural landscapes. Scientific evaluation of landscape resources is significant for preserving the authenticity and integrity of national parks. Taking Qianjiangyuan National Park System Pilot Zone as an example, this research investigated the willingness of internal group (residents and administrative staff) and external group (tourists) to pay for a hypothetical market project based on the pilot zone via Contingent Valuation Method to acquire the monetized value of landscape resources in the national park, and applied Logistic Regression to analyze the influencing factors. The results show ...

In 2022, the insurance industry made a whopping USD 6 trillion globally—more than the entire economy of big countries like Japan and Germany. A new study, published in The Journal of Finance and Data Science, looked at how technology, especially big data, is shaking things up in insurance. Big data means using a lot of information to make better decisions. The study found that by using big data, insurance companies can understand risks better, offer fair prices and keep customers happier. “What's surprising is how fast insurance companies are jumping on the big data bandwagon,” says first ...

Light, as an electromagnetic field, has two essential components: amplitude and phase. However, optical detectors, usually relying on photon-to-electron conversion (such as charge-coupled device sensors and the human eye), cannot capture the phase of the light field because of their limited sampling frequency. Fortunately, as the light field propagates, the phase delay also causes changes in the amplitude distribution; therefore, we can record the amplitude of the propagated light field and then calculate the corresponding phase, called phase recovery. Some common phase ...

A University of Queensland-led study has found humans can tell if chickens are excited or displeased, just by the sound of their clucks.   Professor Joerg Henning from UQ’s School of Veterinary Science said researchers investigated whether humans could correctly identify the context of calls or clucking sounds made by domestic chickens, the most commonly farmed species in the world. “In this study, we used recordings of chickens vocalising in all different scenarios from a previous experiment,” ...

A previously unidentified genetic mutation in a small protein provides significant protection against Parkinson’s disease and offers a new direction for exploring potential treatments, according to a new USC Leonard Davis School of Gerontology study. The variant, located in a mitochondrial microprotein dubbed SHLP2, was found to be highly protective against Parkinson’s disease; individuals with this mutation are half as likely to develop the disease as those who do not carry it. The variant form of the protein is relatively rare and is found primarily in people of European descent. The findings appear on January 3, 2024, in the journal Molecular Psychiatry. First ...

Plastic litter is a growing problem around the world, and new research shows that the bottom of Lake Tahoe is no exception. In one of the first studies to utilize scuba divers to collect litter from a lakebed, 673 plastic items were counted from just a small fraction of the lake.   In the study, published in the November issue of the journal Applied Spectroscopy, researchers from DRI and the UC Davis Tahoe Environmental Research Center teamed up with the nonprofit Clean Up the Lake to take a close look at the litter. First, ...

Infants born extremely prematurely need to get enrichment as an addition to breast milk. But does it make any difference whether the enrichment is made from breast milk or cow’s milk when it comes to the risk of severe complications in children? This has been investigated by a large clinical study led from Linköping, Sweden. Infants born extremely prematurely, between weeks 22 and 27 of pregnancy, are among the most vulnerable patients in healthcare. The risk of serious complications is very high. Almost one in four extremely premature babies die before the age of one. There is strong research support for giving breast ...

A new analysis of fossils believed to be juveniles of T. rex now shows they were adults of a small tyrannosaur, with narrower jaws, longer legs, and bigger arms than T. rex. The species, Nanotyrannus lancensis, was first named decades ago but later reinterpreted as a young T. rex. The first skull of Nanotyrannus was found in Montana in 1942, but for decades, paleontologists have gone back and forth on whether it was a separate species, or simply a juvenile of the much larger T. rex. Dr Nick Longrich, from the Milner Centre for Evolution at the University ...

As the world moves away from gas towards electricity as a greener power source, the to-do list goes beyond cars. The vast global manufacturing network that makes everything from our batteries to our fertilizers needs to flip the switch, too. A study from UChicago chemists found a way to use electricity to boost a type of chemical reaction often used in synthesizing new candidates for pharmaceutical drugs. Published Jan. 2 in Nature Catalysis, the research is an advance in the field of electrochemistry and shows a path forward to designing ...

Unfortunately, WM ...

In the quest to understand the potential for life beyond Earth, researchers are widening their search to encompass not only biological markers, but also technological ones. While astrobiologists have long recognized the importance of oxygen for life as we know it, oxygen could also be a key to unlocking advanced technology on a planetary scale. In a new study published in Nature Astronomy, Adam Frank, the Helen F. and Fred H. Gowen Professor of Physics and Astronomy at the University ...

Plants have to be flexible to survive environmental changes, and the adaptive methods they deploy must often be as changeable as the shifts in climate and condition to which they adapt. To cope with drought, plant roots produce a water-repellent polymer called suberin that blocks water from flowing up towards the leaves, where it would quickly evaporate. Without suberin, the resulting water loss would be like leaving the tap running. In some plants, suberin is produced by endodermal cells that line the vessels inside the roots. But in others, like tomatoes, suberin is produced in exodermal cells that sit just below ...

After the last embers of a campfire dim, the musky smell of smoke remains. Whiffs of that distinct smokey smell may serve as a pleasant reminder of the evening prior, but in the wake of a wildfire, that smell comes with ongoing health risks. Wildfire smoke is certainly more pervasive than a small campfire, and the remnants can linger for days, weeks and months inside homes and businesses. New research from Portland State’s Elliott Gall, associate professor in Mechanical and Materials Engineering, examined how long harmful chemicals found in wildfire smoke can persist and the ...

LA JOLLA, CA—Identifying new ways to target proteins involved in human diseases is a priority for many researchers around the world. However, discovering how to alter the function of these proteins can be difficult, especially in live cells. Now, scientists from Scripps Research have developed a new method to examine how proteins interact with drug-like small molecules in human cells—revealing critical information about how to potentially target them therapeutically. The strategy, published in Nature Chemical Biology on January 2, 2024, uses a combination of chemistry and analytical techniques to reveal the specific places where proteins and small molecules bind ...

Respiratory syncytial virus (RSV) vaccines recently approved for people 60 and older would dramatically reduce the disease’s significant burden of illness and death in the United States if they were widely adopted like annual influenza vaccines, a new study has found. A high level of RSV vaccination would not only potentially reduce millions of dollars in annual outpatient and hospitalization costs but would also produce an economy of scale with individual shots being delivered at a relatively modest cost of between $117 and $245 per dose, the study said. The vaccines are currently covered by most private insurers without ...

Reston, VA—PET imaging with 68Ga-FAPI can more effectively detect and stage pancreatic cancer as compared with 18F-FDG imaging or contrast-enhanced CT, according to new research published in the December issue of The Journal of Nuclear Medicine. In a head-to-head study, 68Ga-FAPI detected more pancreatic tumors on a per-lesion, per-patient, or per-region basis and led to major and minor changes to clinical management of patients. In addition to enhancing precise detection of pancreatic cancer, 68Ga-FAPI ...
